When The Audible Doctor picks up a microphone, you’d best get to stepping; otherwise, you risk becoming the target of his 16 Bars of Death. The official remix of a cut off his just-released Winter Tape, this version of the record finds the Brooklyn rapper/producer swapping his original, chopped-soul-sample beat for a chillier brass-laced groove. That shift in tone doesn’t diminish the impact of his lyrical assault, nor that of Panhandle State emcee J NICS (the latter making his first DJBooth appearance of 2013 after being featured a whopping 27 times last year). Fans can find Bars of Death (Remix), along with the album rendition, the a cappella and the instrumental, on Audible Doctor’s new Remix Pack, available now for free digital download via AudioMack.
